Definitions
- the present invention relates to an inhalation device for use in the administration of medicament to a patient.
- the device has a mouthpiece, which is reversibly retractable from a storage position located inside the body of the device to a dispensing position in which the mouthpiece protrudes from the body of the device.
- inhalation devices in the administration of medicaments, for example in bronchodilation therapy, is well known.
- Such devices generally comprise a body or housing within which a medicament container is located.
- a mouthpiece or nozzle is typically provided, wherein 'in use' the mouthpiece communicates with the medicament container to allow passage of medicament from the source to the mouthpiece and thence, to the patient.
- the body of the device is held by the patient and the mouthpiece (or nozzle) of the inhalation device is placed in the mouth (or nose) of the patient.
- the patient inhales, thereby causing transfer of medicament from the medicament container to the interior of the body of the patient.
- the mouthpiece When not in use it is desirable, from a hygiene standpoint, that the mouthpiece is provided with some kind of protective cover.
- the cover desirably acts both to prevent build-up of dirt on the mouthpiece and to prevent ingress of dirt into the body of the device through the mouthpiece, which might then be subject to inhalation by a patient.
- a protective cap which acts as a protective cover.
- the cap may either be an entirely separate element or it may be joined to the body of the device in some way.
- a protective cap As an alternative to the use of a protective cap, one might envisage a device having a mouthpiece which is reversibly retractable from a storage position in which the mouthpiece is contained within the body of the device to a dispensing position in which the mouthpiece protrudes from the body of the device.
- the body of the device itself acts as the protective cover when the mouthpiece is in the storage position.
- the mouthpiece cover is thus an integral part of the inhalation device, avoiding contamination problems of prior art inhalation devices caused by the loss of removable mouthpiece covers.
- GB-A-2,074,454 describes an inhalation device comprising a tubular body adapted for detachable fitting to an aerosol container.
- a mouthpiece is provided, which is movable from a storage position to a dispensing position by means of a cap, rotatably mounted on the tubular body, which has actuating means associated therewith.
- the cap and tubular body are provided with openings of similar dimensions. Manual rotation of the cap to bring the openings into register causes the actuating means to move the mouthpiece to the dispensing position in which the mouthpiece protrudes from the body of the device. Conversely, rotation of the cap by the user to bring the openings out of register causes the mouthpiece to be moved to the storage position in which the mouthpiece is contained within the body of the device.
- the inhalation device is arranged to allow movement of the mouthpiece from the storage to dispensing position (and vice-versa) by a one-handed operation.
- the device described in GB-A-2,074,454 would be very difficult to operate by means of a one-handed operation since it requires a rotatory movement of the cap relative to the body. This would normally require the user to hold the body in one hand, the cap in another and thence, to perform the required relative rotatory movement.
- the Applicant has now found that the desired one-handed operation can be facilitated where the device is shaped for ease of grip by the palm and fingers of one hand and where the mouthpiece is actuable by a motion of the thumb of the same hand.
- One-handed operation is thus, for example, achievable if the user holds the body of the device in the palm of a partially cupped hand and employs the thumb to provide movement to the mouthpiece actuator, thereby causing actuation of the mouthpiece.
- EP-A-0 028 929 describes an inhalation device comprising a mouthpiece reversibly movable from a storage to an in use position.
- an inhalation device for dispensing medicament comprising
- the body is shaped to be holdable in one hand and the mouthpiece actuator is actuable in response to a motion of the thumb on the same hand.
- the motion of the thumb suitably, but not necessarily, involves contact, and typically engagement, of the thumb with the mouthpiece actuator resulting in the movement thereof.
- the body is shaped to be holdable in the palm of one hand.
- the body is shaped to be holdable in the palm and by at least one of the fingers of one hand.
- the body is shaped to be holdable by a plurality of the fingers of one hand.
- the mouthpiece actuator is coupled to the mouthpiece such that movement of said mouthpiece actuator in a first direction moves the mouthpiece towards said storage position and movement of the mouthpiece actuator in an opposing direction moves the mouthpiece towards said in-use position.
- 'mouthpiece' is used in a generic sense to mean an element shaped such as to be insertable into the mouth or nose of a patient for inhalation therethrough.
- the mouthpiece actuator and mouthpiece are coupled by a coupling mechanism.
- the coupling mechanism comprises a rack and pinion mechanism.
- the coupling mechanism comprises a hinged lever mechanism.
- the medicament carrier is within the body. In another aspect the medicament carrier is attachable to the exterior of the body.
- the mouthpiece actuator and mouthpiece are directly coupled.
- the mouthpiece actuator is a rotatable turning device coupled to the mouthpiece.
- a hinge mounting connects the mouthpiece to the body.
- the hinge mounting is sprung such as to bias the mouthpiece to the in-use position.
- the mouthpiece is comprised of an elastic material.
- the mouthpiece is provided with a cover comprised of an elastic material.
- the inhalation device additionally comprises a curtain arrangement contactable by the mouthpiece on movement of the mouthpiece from the storage to the in-use position. More preferably, the curtain arrangement comprises a plurality of curtains comprised of an elastomeric material.
- the mouthpiece actuator is provided with a safety trigger mechanism to prevent accidental actuation thereof.
- At least a portion of the mouthpiece actuator is shaped for ease of grip by the user.
- At least a portion of the mouthpiece actuator has a friction-enhancing coating.
- the device is provided with a dose counter, which indicates the number of doses dispensed from or remaining in the container. More preferably, the dose counter comprises an indexing mechanism actuated by a predetermined movement of the medicament container relative to the body.
- the medicament container is an aerosol or a dry-powder container.
- an inhalation device provided herein for dispensing medicament.
- Figures 1a and 1b shows a first inhalation device herein comprising a body 10 having an end cap 16, wherein the end cap 16 is reversibly attached to the body 10 by a snap fit mechanism 30,32.
- a medicament container 20 Within the body 10 there is provided a medicament container 20, and integral therewith a mouthpiece 90.
- cover 50 which comprises an arrangement of elastomeric flaps 52, 54 forming a hygienic curtain.
- cover 50 which comprises an arrangement of elastomeric flaps 52, 54 forming a hygienic curtain.
- the integral medicament container 20 and mouthpiece 90 are mounted for translational movement on guide rails 60, 62.
- An outer face of the medicament container 20 is provided with a series of teeth forming a rack 70, which is in communication with first wheel 72 mounted for rotation on the body 10 thereby forming a rack and pinion mechanism.
- the first wheel 72 also communicates with second wheel 74, which is also mounted for rotation on the body 10. Rotation of the second wheel 74 is rotationally coupled to that of drive lever 76, which protrudes from the body 10 making it user accessible.
- Actuation of the device from the storage position (shown in Fig. 1a) to the in-use position (shown in Fig. 1b) is achievable by a user-driven actuation of the drive lever 76.
- this can be achieved by a one-handed operation wherein the body 10 of the device is gripped between palm and fingers and the drive lever 76 is rotated by a motion of the thumb. It may be seen that rotation of the device lever 76 results in similar rotation of the second wheel 74 and opposite rotation of the first wheel 72, which engages with the rack 70 on the medicament container thereby driving the integral medicament container 20 and mouthpiece 90, upwardly along the guide rails 60, 62 to the in-use position. Ejection of the medicament container 20 from the body 10 is prevented by stops 64, 66.
- the mouthpiece 90 impacts with, and causes a parting, of the protective curtain arrangement 52, 54.
- the curtains 52, 54 may be provided with a friction cleaning surface or coating such that the mouthpiece is cleaned of any dust particles, dirt etc., when it contacts the curtains. Deactivation of the device is achievable by the reverse rotation of the drive lever 76.
- Figures 2a and 2b show a second inhalation device herein having an actuation mechanism (not shown in detail) similar to that of the device of Figures 1 a and 1b.
- the device comprises a body 110 having a reversibly removable end cap 116. Within the body there is provided an integral medicament cartridge (not visible) and mouthpiece 190.
- a protective cover 150 is provided to the end cap 116, wherein the cover 150 prevents ingress of dirt and contamination to the mouthpiece 190 within the body 110.
- the drive lever 76 of the device of Figures 1 a and 1b is replaced by a rotationally mounted drive cylinder 176, which has a grooved surface for ease of grip.
- the body 110 is shaped for ease of grip within the palm of a user's hand and the drive cylinder 176 is arranged for ease of rotation by a thumb motion. Actuation of the device is achievable by rotation of the drive cylinder 176 towards the end cap 116 and deactivation is achievable by the reverse rotatory movement.
- Figures 3a and 3b shows a third inhalation device herein comprising a body 210 having a reversibly detachable side position 216, which is shaped for ease of grip.
- a medicament container 220 Within the body 210 there is provided a medicament container 220.
- mouthpiece 290 which communicates with the medicament container through a connecting passage 225 when the mouthpiece is in the in-use position.
- the mouthpiece 290 is mounted on worm 270, such that the worm 270 is rotationally movable therewithin.
- the worm 270 is provided at the lower end with a worm drive wheel 272, which communicates with a second wheel 274 mounted on the body 210, which second wheel 274 communicates with a motor drive wheel 276.
- the motor drive wheel is driven by motor 277 powered by battery 278.
- a user accessible switch 279 is provided for actuation of the motor 278.
- the stub 292, and hence mouthpiece 290 is mounted on movable guide rails 260, 262 having first and second end stops 264, 266 corresponding respectively to the mouthpiece storage and in-use positions.
- the upper end 266 of the movable guide rail arrangement 260, 262 is attached to a sliding door 250.
- the sliding door 250 is closed when the mouthpiece 290 is in the storage position thereby forming a protective cover.
- the door 250 is slidably openable in response to actuation of the mouthpiece 290, thereby allowing the mouthpiece 290 to protrude through the door opening.
- Actuation of the device from the storage position (shown in Fig. 3a) to the in-use position (shown in Fig. 3b) is achievable by user actuation of the switch 279. It may be appreciated that the device as a whole is shaped for one-handed operation involving gripping of the end cap 216 by the fingers and thumb actuation of the switch 279.
- the motor 277 rotationally drives motor drive wheel 276, in turn causing rotation of the second wheel 274, worm drive wheel 272 and hence worm 270.
- the upward rotational movement of the worm 270 causes the mouthpiece 290 and stub 292 thereon to be driven upwards along a path defined by the axis of rotation of the worm 270.
- the stub 292 is mounted on the guide rail arrangement 260, 262, it may be seen that the upwards movement of the stub 292 causes the shaped guide rails 260, 262 to be driven sideways (from left to right as shown), hence enabling opening of the sliding door 250, which is itself attached to the upper end 266 of the guide rail arrangement 260, 262.
- Deactuation of the device is achievable by a second actuation actuation of the switch 279, which results in the opposite motor-driven rotation of the gear assembly 272, 274, 276 and worm drive 270.
- Figures 4a, 4b and 4c show a fourth inhalation device herein comprising a disk-shaped body 310.
- actuation pads 360, 362, 364 At three equally spaced positions on the periphery of the disk-shaped body 310 there are provided actuation pads 360, 362, 364.
- the pads 360, 362, 364 are shaped for ease of grip by a user.
- Three equally spaced slits are also provided on the periphery of the body 310 for receipt of actuating pins 314, 316, 318 mounted on the interior of each pad 360, 362, 364, which pins 314, 316, 318 protrude into the body 310.
- FIG. 4c shows a device in which pad 360 has been compressed moving pin 314 into the body 310 and into contact with plate 370, which has thus been rotated.
- a medicament container 320 and integral therewith a mouthpiece 390.
- the mouthpiece 390 is connected to the generally disk-shaped plate 370 by pivotally mounted arms.
- Figures 4a thus shows arm 392 mounted to the plate 370 at pivot point 394, which arm is itself mounted to mouthpiece 390.
- the arm 392 contacts a triangular cam surface 396 provided on the body 310.
- the plate 370 is rotated the contact of the arms 392 with the camming surface results in the arms 392, and hence the mouthpiece 390, being urged upwardly towards a circular opening 312 in the body.
- the opening 312 is closed off by an iris shutter mechanism comprising three shaped doors 350, 352, 354 capable of forming a circular closure.
- Each of the doors 350, 352 354 is pivotally mounted to the generally disk-shaped plate 370 at pivot points 351, 353 and 355.
- the iris closure is generally urged towards the closed position by leaf spring mechanisms 394, 396, 398.
- the rotation of the pate 370 relative to the body 310 may, thus, be seen to allow for opening and closing of the iris shutter mechanism.
- Rotation of the plate 370 is initiated by its drivable contact by one or more of the actuating pins 314, 316, 318.
- a lock mechanism is further provided, which allows for reversable locking of the device in the 'in-use' (i.e. iris shutter open and mouthpiece protruding) position.
- the locking mechanism comprises locking arm 340 mounted at a first end at pivot point 342 to the body 310.
- the second end of the arm is provided with a stub 344, which is mounted for travel on irregular-shaped track 346 provided in the plate 370.
- the stub 344 moves along the track 346 until it is retainably received by valley 348 in the track 346, which corresponds to the locking position. Unlocking is achieved by further rotation of the plate 370, which allows for release of the stub 344 from the valley 348 in the track 346.
- Actuation of the device from the storage position (shown in Figures 4a and 4b) to the in-use position (shown in Figure 4c) is achievable by a user-driven compression of one or more of the actuating pads 360, 362, 364. It will be appreciated that such compressive force may be conveniently achieved by a user holding the body 310 of the device in a cupped hand and using the thumb to squeeze down one of the actuating pads 360, 362, 364. Compression of an actuating pad 360, 362, 364 results in an actuating pin 314, 316, 318 being pushed into the body 310 of the device.
- the actuating pin 314, 316, 318 contacts the plate 370 causing rotation thereof, which rotation in turn results in the opening of the iris shutter mechanism, and ejection of the mouthpiece 390 from the opening 312 thereby revealed in the body 310.
- the iris shutter and mouthpiece are locked into the 'in use' position by the hereinbefore described locking mechanism. Deactuation is achieved by application of further compressive force to an actuating pad 360, 362, 364 resulting in further insertion of a pin 314, 316, 318 which in turn further rotates the plate 370, and, thus, results in unlocking of the lock mechanism.
- the plate 370 may then rotate back to its start position under the influence of the spring mechanism 394, 396, 398 which also causes closing of the iris shutter.
- Figures 5a, 5b and 5c show a first inhalation device herein comprising a body 410 having an end cap 416, wherein the end cap 416 is reversibly attached to the body 410 by a snap fit mechanism 430, 432.
